Abstract
A method and apparatus for separation of H2 gas from a gaseous mixture utilizing an H2 gas permeable metallic membrane supported directly on a porous substrate made up of at least one porous polymeric hollow fiber. In accordance with one preferred embodiment, the porous substrate is made up of a plurality of porous polymeric hollow fibers, forming a porous hollow fiber membrane. In accordance with one embodiment, a cooling fluid is disposed in contact with the hollow fiber, thereby enabling advantageous operation of the H2 gas separation process at elevated temperatures in the range of about 200° F. to about 800° F.
